Tips on How to Program (or Reprogram the Item) Plus Compatibility with other Remotes
- Setting up the item is very easy. You only need to open the panel on the rear of the garage door motor to gain access to the PURPLE programming button. With the remote in one hand, use the other hand to press the PURPLE programming once and release.
- At this point, the light will start flashing. Using your other hand, press and hold down the button on the remote until the door opens. Once it does, release the button on the remote. The remote is programmed and all of the other remotes will still work as normal.
It only requires less than 10 minutes to install.
